Hello

when process is creating a see in jbpm-console many instance with the same id and when I click on one of them I recived:

16:29:55,126 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/gwt-console-server].[Resteasy]] (http-localhost-127.0.0.1-8080-5) Servlet.service() for servlet Resteasy threw exception: org.jboss.resteasy.spi.UnhandledException: javax.persistence.NonUniqueResultException: result returns more than one elements

my code is :

                                    ut = (UserTransaction) new InitialContext()
                                    .lookup("java:comp/UserTransaction");
                                    ut.begin();

                                    StatefulKnowledgeSession session = JbpmAPIUtil.getSession();
                                    JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(session);

                                    Map<String, Object> paramsOut = new HashMap<String, Object>();
                                    paramsOut.put(EProcessParams.USER_ID.getValue(), ...);

                                    ProcessInstance pi = session.startProcess(
                                                            EProcessParams.PROCESS_ID.getValue(), paramsOut);

                                    Thread.sleep(3000);

                                    TaskSummary task = JbpmAPIUtil.startTask(pi.getId(), user,
                                                            Egroup);

                                    Map<String, Object> params = new HashMap<String, Object>();
                                    ...

                                    JbpmAPIUtil.completeTask(pi.getId(), task.getId(), user,
                                                group, nextUser,
                                                nextGroup, params);

                                    ut.commit();

                                    logger.dispose();
